Quote: Aviation Partners Boeing has officially launched the 767-300ER Blended Winglet program with FAA certification anticipated in the fourth quarter of 2008. Three airlines on three different continents have already placed firm orders for 68 767-300ER Blended Winglet systems. The benefits of Blended Winglets for 767-300ER operators -- both passenger and freighter versions -- include average annual fuel savings per aircraft of 350,000 gallons (1,330,000 liters), payload improvements of up to 12,000 pounds (5,447 kilograms) and a range boost of up to 360 nautical miles (667 km).

There's a thread concerning AA's possible involvement in the winglet program for its 767s. This states there are 68 orders so far. American has 58 763s and 15 762s. Maybe a test program will be done on the 767s, like the 752s and 738s before a decision was made to retrofit all of them.

With the increased focused on climate change and the adverse affect on the climate from increased flying demand, I wonder if there would be a case for an airline to seek government funding to help them tackle climate change by adapting winglets.
Does this mean the 767 with winglets will only be able to travel in USA, with other countries aviation regulatiry bodies needing approval also, such as CAA within UK etc, or are they cleaered to operate worldwide?

Quoting GeorgiaAME (Reply 7): So what happens to the 764s, if wing tips outperform the racked version? (Or visa versa?)
Boeing added the raked wing for a reason. it has been said that the T7 has the most areodynamic wing in the world, including the tip. i believe the 764 wings will remain unchanged

I am pretty sure that the 2nd airline is going to be LAN. I have heard that they and/or AA provided the testbed aircraft for Aviation Partners 767 winglet development.
The 3d airline... your guess is as good as mine. Let's look for OneWorld partner with a 767 fleet. Maybe Qantas with 29 of those?

On another note:
"APB has already certified its patented Blended Winglet technology for the Boeing Business Jet, 737-800, 737-700, 737-300, and 757-200. APB is also currently in the process of certifying Blended Winglets for the 737-900 and 737-500."
What ever happened to WestJet's plan to get BW on their 737-600 fleet?

Does it really take 18 months to get this project certified? Late 2008 is a long time to wait. Heck, Boeing is getting the 787 certified faster than that.

The blended winglets do not outperform the raked winglets. The blended winglets are a compromise to get winglet benefits without drastically increasing the span of the aircraft.

Hamlet69,
This one i'm going to trust you on as your info is superb and reliable. Add DL to the list as they'll be flying them transpac soon and they'll need that extra range.

Quoting Hamlet69 (Reply 12): What ever happened to WestJet's plan to get BW on their 737-600 fleet?
They abandoned it:
"After careful analysis, we elected not to install winglets on our 600-series aircraft as the cost and time associated with their installation on these aircraft was not warranted as they are primarily used for short-haul routes."

Quoting KFLLCFII (Reply 20): Well, that makes one from North America, and one from South America. Hamlet69 was first to call LAN, way to go Hamlet.
Thanks! But here's the strange thing:
- APB's press release dated April 23 states that "Three airlines on three different continents have already placed firm orders for 68 767-300ER Blended Winglet systems."
- Two days later, on April 25, American Airlines and APB issue a joint announcement stating the airline's commitment to test and certify the first 767-300ER winglet, while: "Upon completion of the certification program, American plans to install winglets on its entire fleet of 58 B767-300ER aircraft. . .[snip]"
- Today, May 3, we get the press release that 2wingtips linked to above, stating that LAN has signed up for 8 767-300F kits, and 7 767-300ER kits.
So the question becomes: was LAN not one of the launch customers referred to in the April 23 release, OR has American not signed a firm contract for all 58 kits? Cause it cannot be both. . .

Quoting Vorticity (Reply 15): The blended winglets do not outperform the raked winglets. The blended winglets are a compromise to get winglet benefits without drastically increasing the span of the aircraft.
The first sentence is not quite true. A winglet is just a non-planar span extension. If you lay the winglet down flat and measure the equivalent span extension, it will slightly outperform a raked tip of the same span extension. The winglets also produce less of a bending moment increase and hence, less structural beef-up is required to add them.
25 ANother: Surprised they aren't taking the opportunity to mention the 'environmental' benefits as well. 6% improvement in fuel burn is quite a few tonnes of CO
26 Ikramerica: No, the media needs to actually pay attention. The airline industry has reduced pollution by huge amounts, especially compared to the auto industry.
27 ERAUgrad02: I wonder if UPS/FEDEX/DHL will order these. It will allow them to carry more cargo further. What do you guys think?
28 ANother: Rather, one needs to hit the media over the head with a very large blunt object - but if you don't put it into your press release, which they didn't,
29 UN_B732: I'm surprsied Delta hasn't ordered any - I'm sure it will come however, they push those 763s to the limit.. especially if they want to install AVOD IF
